In response to this effort, Anthony Fieroni (@bvbfan), who makes Plasmoids and works with Qt 5, made a version of kvkbd for Qt 5! See https://github.com/bvbfan/kvkbd
This version will remain online for those who want to use the Qt 4 version, and for historical reasons.
This is an AppImage for kvkbd
, which I still feel (as of 10/2020) to be the best on-screen keyboard for GNU/Linux.
KDE abandoned it and didn't ugrade it for Qt 5. Most distros have dropped Qt 4 and KDE 4, both of which are dependencies to some extent, leaving kvkbd
abandonware that is extremely difficult, if not functionally impossible, to compile. I rescued it with AppImages. See Rescuing kvkbd.
The AppImage is โ30MB. It has some issues, you need the Oxygen icons. See the Medium for more and workarounds.
